Kinetics of HDS Reaction for South Pars Gas Condensates

: In this research, a systematic investigation was carried out to determine kinetics of HDS reaction of Iranian gas condensate using a commercial catalyst (Co-Mo/ y -Al203). In this way, process conditions were optimized. Experiments were carried out in a trickle bed micro reactor (10 cc catalyst) at 280-340 °C, 40-50 bar, Liquid hourly space velocity (LHSV) of 1-5 h , H2/Oil ratio of 125 nl/l. Prior to the kinetics tests, by some basic tests, mass transfer effects on chemical reactions were evaluated, and it is found that pore diffusion and film diffusion resistances have a slight effect on the kinetics of chemical reaction, within the operating conditions. Hence, kinetics of HDS reaction was determined by using thiophene as a reference sulfur component, in the form of power low model. The results indicated that thiophene HDS reaction order in gas condensate feed was 1.3 . Also, HDS reaction activation energy was determined to be 77.55 kj/mol. The results of this kinetics model and its simulation can use in optimization of HDS units process conditions and prediction ofproduct specifications with new feeds and different process conditions. It is also useful for designing the reactor of new HDS plants.
